The U.S. Congress is considering a set of bills designed to limit the nation's greenhouse gas (GHG) emissions. This paper complements the analysis by Paltsev et al. (2007) of cap-and-trade bills and applies the MIT Emissions Prediction and Policy Analysis (EPPA) model to carry out an analysis of...

In the absence of significant greenhouse gas (GHG) mitigation, many analysts project that atmospheric concentrations of species identified for control in the Kyoto protocol could exceed 1000 ppm (carbon-dioxide-equivalent) by 2100 from the current levels of about 435 ppm. This could lead to...

We consider the large range of estimated costs of meeting U.S. climate policy targets. Some of this range is due to different studies using different cost measures, and in principle such differences could be eliminated by more careful comparisons and greater transparency in studies that estimate...
